Syracuse, N.Y. -- On Dec. 23, a woman was approached on East Division Street by a 13-year-old boy.

The teenager pulled out a gun and stole her car. The carjacking was one of four robberies the 13-year-old committed in December.

That's according to Syracuse police Sgt. Tom Connellan, who confirmed that authorities have arrested the 13-year-old boy and two other teenagers in connection with four robberies.

The 13-year-old's name is not being released because of his age. He was the only one involved in all four robberies -- a 15-year-old, whose name is also not being released, and Kyire Burgess, 17, have each been connected to only some of them.

The 15-year-old and 13-year-old will be tried in family court.

The first two robberies occurred near Le Moyne College -- the first on Dec. 3 and the second several days later, Connellan said.

In the first robbery, a male student at Le Moyne had his property stolen on Audubon Parkway. In the second, two female students were threatened with a gun and robbed.

The third was on Dec. 18, on Madison Street. A Syracuse University student was assaulted and robbed. The fourth was the carjacking on East Division Street.
